5V Boost Lithium BatteryThe 5V is a stabilized voltage, the error is 5 + 0.5V, the so-called stabilized voltage refers to a stable voltage, that is to say, no matter how much the battery is charged to how many V or how many V the voltage is not going to change, determine the actual voltage of the battery to test the charging port voltage, has nothing to do with the discharging port voltage.

5V Boost Lithium BatteryDischarge port can not charge but the charging port can be discharged, that is, the charging port has a dual function of charging and discharging. 5V is the output voltage, that is, the voltage used to supply power to the device; charging port is the same as the regular ordinary battery function, discharged 2.4 ± 0.3V, full 4.2V ± 0.2V.

5V Boost Lithium BatteryCan be charged with a 4.2V charger can also be charged with a 5V charger, but charging can only be done through the charging port, not to the 5V discharge port. Some buyers asked why the recommended charger for 5V batteries is 4.2V, because the charging port of the battery is equivalent to the function of an ordinary 3.7V battery, there is no difference with conventional batteries. Charging and discharge port voltage, that is, with the 5V output voltage is not related, so there is no charging is not enough power.

5V Boost Lithium BatterySometimes also known as 4.8V or 5.5V batteries, 5V constant voltage batteries, 5V batteries, in fact, are the same product, just different customary call. Currently5V Boost Lithium BatteryThere are two series of working current 1A and 2A, please pay attention to them when purchasing. Devices exceeding the operating current [error ±0.2A] cannot be used properly, especially devices with motors/motors or capacitors/inductors, high-power lamps and lanterns, and so on. If you need higher working current, please purchase5V High Current Buck Seriesor optional4.8V NiMHmaybeLithium Titanate Battery PackThe

All current5V Boost Lithium BatteryThe charging current must not exceed 1C (i.e. capacity value) and must not exceed 2A, please note that the charging current may not be enough or cannot be charged beyond this value. In addition can only use 4.2~5V constant voltage type charger(not charging chip!) Or computer USB port charging, with 9V/12V intelligent variable voltage type may not be able to charge.

this series5V Boost Lithium BatteryIs with a protective plate, full will be automatically cut off, no charging indicator in the case of more charge a while all right, but don't forget to take down all the time to charge oh. Safety first! Recommended to buy a charger with indicator or a model with power display or power display board. 5V series battery charging/discharging port can be discharged at the same time, but does not ensure that it can continue to work, so it is not recommended to use at the same time; the other two ports at the same time is equal to the shunt, the total discharge current shall not exceed the upper limit of the protection board current, or it will be serious heat or even damage the protection board.

Warning:Beware of short circuits when detecting the voltage at the charging port! Once short-circuit will trigger the short-circuit protection action of the booster board, automatically cut off the circuit, and then can not measure the voltage or can only measure a very low non-normal voltage, at this time you need to charge in order to re-activate the booster board, and even need to dismantle the circuit of the battery cell charging and then turn on the circuit for normal use.
